We are getting errors like: 'Cannot attach file -------.jpg: Unknown server error (###).. when we try to upload images. The proper permissions are in place. It appears to affect jpegs the most. I was reading that in some cases spaces in the names of the files can cause issues, but when I change a name with spaces to not having spaces the error still occurs.

We need to solve this as we upload a large amount of files and can't be changing names all the time. Is there any other information out there that we can reference?
